The Columbia Public Works Department owns and operates the sanitary landfill and sells methane collected from 65 gas collection wells to the Columbia Water & Light Department. The Columbia Water and Light Department has operated the LFG energy facility on the landfill property since mid-2008. The on-site LFG energy facility was at 2.1-MW from 2008 to 2013. In 2013, a third generator was installed at the facility resulting in a 1-MW increase in output from the plant. The landfill has an RD&D permit to operate the current disposal cell as well as the next two cells with bioreactor technology which should accelerate gas production. The city installed a heat recovery system in 2011 to utilize the heat byproduct of the electrical production to heat the Material Recovery Facility and two maintenance bays in the Landfill Operation Center and displaced 10,000 gallons of propane with this heat during Winter 2011-2012.
